"The atheist movement, in composition and purpose, has in the last decade failed to demonstrate a meaningful dedication to fighting economic inequality and building a safe space for nontheists regardless of their socioeconomic class," wrote Bristol.

"Despite all their talk of building a better world and upholding diversity, contemporary atheism and humanism's most prominent authors and leaders have been suspiciously silent on the topic of poverty."

According to Bristol, while some local nontheist groups engage in philanthropy to benefit the poor, far too many atheist organizations solely attack religious communities via "self-righteous billboard campaigns."

"While the current movement limits itself to honing arguments and gleefully ridiculing the religious, others who don't share their educational privilege, those in poor communities are often bound by a strong local church," wrote Bristol.

"The last decade is peppered with blatant examples of outright classist language and motivation that has directly distanced the atheist movement from peer religious communities."
